Postmark - Email Service Privacy Overview

Back to Vendor Library

Overview

Postmark differentiates itself from bulk email marketing platforms by focusing exclusively on transactional email — messages triggered by user actions such as password resets, order confirmations, shipping notifications, and account alerts. Built by the team behind Wildbit (now part of ActiveCampaign), it emphasizes delivery speed and inbox placement rates. Postmark operates entirely on the server side, processing emails through its API or SMTP integration without injecting scripts into visitors' browsers.

What This Script Does

Postmark has minimal to no browser-side presence on customer websites. It functions as a backend API service that sends transactional emails when triggered by server-side events. There are no tracking scripts, pixels, or cookies set in visitors' browsers. If any Postmark-related resources appear in a page load, they are typically limited to email tracking pixels embedded within the sent emails themselves (for open rate tracking), not on the website. The service does not collect visitor browsing data, set cookies, or perform any client-side data processing on your website.

Consent & Compliance

Because Postmark operates as a backend email delivery service with no browser-side tracking scripts or cookies, it falls outside the scope of cookie consent requirements for website visitors. The service processes personal data (email addresses, message content) on the server side under a data processing agreement, but this processing is not triggered by or visible to website visitors' browsers. Email-level tracking such as open rates and click tracking is governed separately and applies to email recipients rather than website visitors.

Should You Block This Without Consent?

No. Postmark is an essential backend email delivery service with no browser-side scripts or cookies. There is nothing to block on the client side, as the service operates entirely server-to-server.

Is Postmark GDPR compliant?

Postmark's trackers are classified as essential (strictly necessary), so they are generally exempt from prior consent under the GDPR. You should still list them in your cookie policy and privacy notice so visitors know they are there.
